Dear users, I have a couple of questions before I upgrade to 4.3.3. First of all will the update change my modem firmware? mine is currently at 02.10.04 and will it be a big deal? What tool will I use to jailbreak 4.3.3? My phone is currently jailbroken with greenpoison but I wish to update as newer games require ios 4.2 or above to play. When I do upgrade will it be easiest to just restore as new phone in iTunes then update? or do I have to do something in Tiny Umbrella? my blobs are saved both on Cydia and on pc.
